Field surveys were conducted in bedrooms to investigate the relationship between the environment and sleep quality. Sleep efficiency was relatively low when the average CO2 gas concentration at sleep was low which may be due to the high noise level. The percentage of wake-after-sleep-onset was the lowest under thermally neutral.

Air-conditioners are going to be set up in public elementary schools. The installation rate reached 64% in Tokyo 23 wards in 2007. The increase of energy consumption is a concern as air-conditioner use spreads all over the country. In this study, the forecast of energy consumption until 2030 is illustrated. This is calculated by forecasting the number of classes in which air-conditioners have been installed and the air-conditioning load in each 47 prefectures. In addition, the energy-saving measures such as natural ventilation and Low-e glass are accounted. It is possible to reduce energy consumption to the level of 1990 by 2030, when all the measures and improvement in COP of air-conditioner are taken.

The objects of this study are to observe the detailed distribution of air velocity and CO_2 (carbon dioxide) concentration which is used as tracer gas of coughed air and to calculate advance conditions concerning droplet dispersion counting on relative humidity and pressure. The full scale chamber where the experiment was conducted was modeled and then the experimental conditions were input. The elaborative mock was achieved. The results of CFD illustrated the high CO_2 concentration area and many tiny droplets were observed near the medical doctor. Hence the infection risk was still high when the medical doctor moves.

The globalization of people and things results in the short average distance of the networks and emerging infectious disease can spread immediately after the development in this world. Thus, preventive infection control measures are important. The infection risk should be evaluated to adopt effective infection control measures. In this study, the cough machine that can generate human-like cough to evaluate the infection risk in indoor environments were developed to evaluate infection risk. The cough expired volume, travel distance, velocity, total mass of droplets, and particle size distribution of the droplets of the cough machine were compared with the subject experimental data. The deposition of droplet on facial mucous membranes, such like eyes and a mouth, at various distances and horizontal surfaces at different heights were measured using the cough machine and thermal manikin. It was shown that the number of droplet deposited on the position of facial mucous membranes decrease drastically over 90 cm when the infected person and susceptible person faced each other. On horizontal surfaces, the droplet deposited most at 50-60 cm and more than 90% of the droplet deposited within 90 cm. The number of droplet deposited on the surface under 50%RH condition was larger than that under 30%RH condition. The effect of relative humidity was larger on the near surface because the propagation time is shorter than it takes to deposit on the distant far-surface. We provide experimental evidence to evaluate droplet and contact infection risk that enable to address a question of the relative importance of each infection route.

Partial insulation retrofitting is an effective method for improving thermal insulation in existing houses as its construction cost is lower than that of total insulation retrofitting. This study aimed to clarify the actual conditions of the thermal environment in partially insulated retrofitted houses in summer and winter. Furthermore, the size of insulated areas and heating methods were examined from perspective of energy consumption and health. Field surveys on indoor environments were conducted in an actual partially insulated retrofitted house in Chiba prefecture. Subsequently, we show the effects of different insulation areas and heating methods on energy consumption and health.

To investigate the effect of thermal environment and the ventilation rate on productivity, a subjective experiment was conducted. The conditions were the combination of thermal environment: operative temperature of 25.5°C and 28.5°C; and the ventilation rate: 11m3/(h•p) and 90m3/(h•p). Eleven subjects participated in a 350min exposure and worked on three-digit multiplication tasks for 180min. The percentage of dissatisfied with air quality was higher in the higher temperatures and in the lower ventilation rates. The performance of the task was not significantly different among the conditions. The increase of the level of fatigue was more in the higher temperature condition. Correlation between the percentage of dissatisfied derived from perceived air quality and the fatigue level was obtained. The relationships of the task performance and the satisfaction vote of the indoor environment and the level of fatigue were obtained.

Semi-outdoor environment is defined as a grade of environmental control in thermal environmental planning, falling in between indoor and outdoor environment. Thermal adaptation of occupants, together with building and equipment, needs to be taken into account for planning such environment. Behavioral and psychological adaptation was found to be influential on thermal comfort, and context of thermal environment was found to be important to understand the adaptive process from literature review. Environmental context was categorized into social, architectural, and personal elements. A concept model of adaptive thermal comfort in semi-outdoor environment was proposed. Problems concerning application of existing thermal comfort standards were discussed. Adaptive comfort zone, not comfort temperature, needs to be investigated through field surveys considering the Japanese context such as geographical location, climate, degree of environmental control and general-purpose of the architectural space. Adaptive comfort zone needs to be presented together with the definition of environmental context.

Control principle and evaluation method for thermal environment with the thermal manikin are described in this paper. Under the still air conditions, nude and clothed thermal manikin was exposed to measure skin temperatures and heat loss. Combined heat transfer coefficient for nude conditions were estimated and they were not depended on the surrounding temperatures and its averaged value was 7.9 W/m^2℃. Those at foot and hand were bigger than other parts and thigh and crotch were smaller. The method to calculate PMV from total heat loss was described. Estimation of clo value from heat loss, skin temperature of manikin, and equivalent temperature were discussed here.

To improve indoor air quality, it’s necessary to accurately control the body odor emitted by humans living under various environmental conditions and lifestyles. The purpose of this study was to obtain a better understanding of the effects of changes in physical quantities due to insufficient sleep on the emission of human bioeffluents causing body odor and the perceived air quality. The experiment involved two conditions of sleep time. Different biogenic substance concentrations and sensory evaluations of the odor in the chamber were obtained when the occupants' sleep times was different, even for the same CO2 concentration in the room.

Air temperature and CO2 concentration were measured in classrooms with ventilation system from April 2018 through March 2022. It is assumed that, under the COVID-19 circumstances, windows of the classrooms, where ventilation system was working, were basically kept open throughout a year. The average air temperature at foot level was 11°C during winter period because of cold outdoor air infiltration. The estimated ventilation rate tended to decrease during winter period. However, the estimated ventilation rate per person more than 30 m3/h was obtained in case of half number of pupils in the classroom with Hybrid-Flexible lesson for the whole day.

In order to investigate the effects of extremely low humidity on human health, comfort and performance, subjective experiments were carried out at Technical University of Denmark. Sixty subjects were exposed in climate chambers for 5 hours, performing simulated office work. Four humidity conditions in clean air at 22℃ and 4 conditions in polluted air, 3 of which at constant absolute humidity, were imposed. It was found that 5 hours ofexposure to 15%RH or below in clean air or high air temperature in polluted air is sufficient for the mucous layer of the tear film to become measurably worse. Subjective reports of dry discomfort increased as humidity levels were reduced, although the level of discomfort was never more than mild even at 5%RH. A negative effect of low humidity was found on the performance. The observed increase in blink rate at lower levels of relative humidity may have progressively reduced the rate of visual data acquisition and lead the decreased performance of subjects.
